Fig. 3 is according to the program flow diagram of the preferred embodiment of stuck banknotes detection method of the present invention, and detailed treatment scheme is as follows:
Step S10, picture size detects, and obtains the dimensional data of bank note to be measured.
For example, after image analyzer 14 scans bank note to be measured, obtain the scan image data of bank note; Controller 12 obtains the dimensional data of scan image after scan image data is processed, as image length, width etc.Except the method that the mode of employing image scanning detects, also can adopt other size detection means to detect.
Step S20, judges whether to meet Paper Money Size requirement.That is whether the size that, judges bank note to be measured meets the second above-mentioned predetermined condition.
For example, the image size data (as image length and width) of the bank note to be measured that controller 12 obtains image analyzer 14 in step S10 contrasts with the dimensional data (as the length of individual bank note and width) of this bank note type of storage in reservoir 20, judges whether the picture size of bank note to be measured meets Paper Money Size requirement.If undesirable, forward step S74 to; If met the requirements, forward step S30 to, be for further processing.
Step S30, safety line detects.
Step S40, judges whether to meet safety line feature request.
Controller obtains security thread detector 16 bank note safety line characteristic to be measured (as safety line quantity, safety line signal intensity) at step S30 contrasts with the safety line characteristic (as the safety line quantity of individual bank note, safety line signal intensity etc.) of this preset bank note type in reservoir 20, judges whether bank note to be measured meets the safety line feature request of bank note.If undesirable, forward step S74 to; If met the requirements, forward step S50 to, be for further processing.
Step S50, transmitted light detects.
By the optical transmitting set in transmitted light detector 18, the irradiation light that sees through bank note, the transmitted light data of output bank note are irradiated, by optical receiver, received in the subregion of bank note; Common optical transmitting set, optical receiver is infrared transmitter, infrared light receiver.
Step S60, judges whether to meet light intensity requirement.
Transmitted light data analysis step S50 being obtained by controller 12, calculate the weighted mean value of transmitted light data, be called for short weighted mean value, this weighted mean value has reduced the impacts of region on bank note light transmission such as watermark in bank note, striped, pattern, safety line, can reflect preferably the relation being inversely proportional between bank note light transmission and banknote thickness.Because the stronger transmitted light data of transmitted light are larger, the more weak transmitted light data of transmitted light are less, therefore can utilize the transmitted intensity of the weighted mean value representation bank note that represents transmitted light size of data, hereinafter to be referred as light intensity.If meet light intensity requirement, forward step S72 to; If do not meet light intensity requirement, forward step S74 to.
Step S72, bank note is not re-opened.
When picture size, safety line feature and the transmitted intensity of bank note to be measured all meet the requirements, illustrate that bank note to be measured is individual bank note.
Step S74, stuck banknotes.
When any one in picture size, safety line feature and the transmitted intensity of bank note to be measured is undesirable, stuck banknotes is described.
This embodiment is by detecting the size of scan image, can detect bank note non-just to time the phenomenon of re-opening; By detecting the accordance of bank note safety line, can detect bank note except safety line the stuck banknotes completely relatively time; By bank note transmitted intensity size detection banknote thickness, change, thereby detect stuck banknotes.By the detection to the multiple features of bank note, solved the deficiencies such as single feature detection accuracy is not high, testing result is unstable, guaranteed the reliability of testing result.
Below in conjunction with Fig. 4, illustrate whether the picture size of bank note to be measured meets the determination methods that Paper Money Size requires, and the method comprises:
Step S22, reads the Paper Money Size data of individual bank note of storing in reservoir.
Controller, by detecting the processing of data, as scan image data, identifies the bank note type of bank note to be measured, and the concrete disposal route of paper money recognition does not belong to content of the present invention, does not repeat them here.According to the type of identifying bank note, read individual bank note dimensional data being stored in reservoir 20, comprise presetting length and the preset width of individual bank note.
Executing after this step, then judging according to the dimensional data of bank note to be measured whether the size of described bank note to be measured meets above-mentioned the second predetermined condition of mentioning, for example, can be by carrying out following step S24 and step S26 realizes.
Step S24, judges whether the image length of bank note to be measured is greater than the presetting length of individual bank note.
Step S26, judges whether the picture traverse of bank note to be measured is greater than the preset width of individual bank note.
The picture traverse of controller 12 to bank note to be measured and the preset width of individual bank note contrast, if the picture traverse of bank note to be measured is greater than the preset width of individual bank note, the picture size that bank note to be measured is described does not meet Paper Money Size requirement, forwards the step S74 in above-described embodiment to; Otherwise, forward the step S30 in above-described embodiment to.
The execution sequence of above-mentioned steps S24, S26 can be adjusted as required, such as also can first performing step S26, perform step again S24, or step S24 and S26 carry out simultaneously, no matter these two steps by which kind of order are carried out, and whether the picture size that can realize detection bank note to be measured meets the object of the dimensional requirement of individual bank note.
Because two or two above bank note are when overlapping, overlapping paper is difficult to alignment in length and/or width, therefore, by obtaining the picture size of bank note to be measured, comprise image length and the picture traverse of bank note to be measured, presetting length and/or the preset width of the image length of bank note to be measured and/or individual bank note of picture traverse and its corresponding types are contrasted, thereby can judge whether bank note to be measured is re-opened from the physical dimension of bank note.
The whether satisfactory determination methods of safety line feature that bank note to be measured is described below in conjunction with Fig. 5, the method comprises:
Step S42, judges whether bank note safety line quantity to be measured equals to set quantity.
The safety line quantity of controller to bank note to be measured, compares with the safety line quantity that is preset at this bank note type to be measured in reservoir 20, if equated, illustrates and meets safety line requirement, forwards step S44 to; If unequal, illustrate and do not meet safety line requirement, forward the step S74 in above-described embodiment to.
Step S44, judges that whether described safety line signal intensity is consistent with default safety line signal intensity.
If consistent, explanation meets safety line feature request, forwards the step S50 in above-described embodiment to; If inconsistent, illustrate and do not meet safety line feature request, forward the step S74 in above-described embodiment to.
It should be noted that, above-mentioned step S42 and step S44 can only carry out one, also can two all carry out, and when all carrying out for two, the order of step S42 and step S44 is variable.
Generally, the safety line number of signals detecting by security thread detector 16, judges safety line quantity.Such as, the safety line quantity of individual bank note of certain type is one, when many safety line signals being detected, stuck banknotes is described, as security thread detector 16 detects in Fig. 7 a two safety line signals 30,32 o'clock, can determine that bank note to be checked has two safety lines 34,36 at least, be at least that two pieces of paper coin is overlapping.But, if detected when bank note safety line signal to be measured is one, as security thread detector 16 detects the signal 40 as shown in Fig. 7 b, can not determine that bank note to be measured do not re-open, reason is, under extreme case, when the above bank note of two or two are overlapping, its safety line separately also may be completely overlapping, therefore, also need to judge safety line quantity from the intensity of safety line signal.When the bank note safety line number of signals to be measured detecting and intensity are all consistent with setting value, just can obtain bank note safety line quantity to be measured consistent with setting value.Be subject to bank note newness degree difference, the different impact of bank note version, the safety line detection signal strength of same type bank note changes and can very greatly, therefore, detect time error larger by signal intensity.Conventionally only utilize the safety line number of signals of bank note to be measured to judge whether its safety line feature meets individual bank note requirement, utilizes the detection to other features of bank note to be measured simultaneously, get rid of two or two above bank note safety lines overlapping situation completely.
Because the position of safety line on every bank note can change within the specific limits, therefore, when the above bank note of two or two are overlapping, the safety line of every bank note is difficult to overlap completely, therefore, by obtaining bank note safety line feature to be measured, the safety line feature of the safety line feature of bank note to be measured and individual bank note of its corresponding types is contrasted, thereby can judge whether bank note is re-opened.
Below in conjunction with Fig. 6, illustrate whether the transmitted intensity of bank note to be measured meets the determination methods that light intensity requires, and the method comprises:
Step S52, calculates weighted mean value.
The transmitted light data analysis that step S50 is detected, reduce light transmission abnormal area, comprise easy transmission region, as the pattern-free of bank note or texture region, and be difficult for transmission region, the impact on bank note light transmission such as pattern as obvious in safety line, color, try to achieve the weighted mean value of transmitted light data, be weighted mean value, wherein, easily transmission region, be difficult for transmission region the weights of corresponding light data smaller.
Step S54, judges whether weighted mean value is greater than intensity threshold.
Because the thicker light transmission of bank note is poorer, the thinner light transmission of bank note is better, therefore by can reflect the weighted mean value of banknote thickness treat side bank note whether meet light intensity require judge; If weighted mean value is greater than intensity threshold corresponding to this bank note type being preset in reservoir 20, illustrate that the transmitted intensity of bank note to be measured meets the light intensity requirement of individual bank note, forwards step S72 (referring to Fig. 3) to; If weighted mean value is less than intensity threshold, illustrate that the transmitted intensity of bank note to be measured does not meet the light intensity requirement of individual bank note, forwards step S74 (referring to Fig. 3) to.
Below in conjunction with definite method of Fig. 8 a, Fig. 8 b explanation intensity threshold.Because bank note is after being used a period of time, the dust of its surperficial adhesion declines its printing opacity degree, and therefore, the light transmission of old coin is poorer than new coin; Meanwhile, because the thicker light transmission of bank note is poorer, the thinner light transmission of bank note is better, therefore, the light transmission of individual bank note is higher than the light transmission of two pieces of paper coin.Based on above-mentioned principle, the light transmission of individual new coin, individual old coin, two new coin, two old coin, from arranging to weak by force, is followed successively by individual new coin, individual old coin, two new coin, two old coin.Therefore, if the intensity threshold of setting can be distinguished the light transmission difference of individual old coin and two new coin, just can be take intensity threshold as whether re-opening with reference to judging bank note.
By the infrared transmitter in transmission detector 18, along direction 54 shown in Fig. 8 a, irradiated the region 52 of bank note 50 to be measured, by infrared light receiver, received the irradiation light that sees through bank note, the transmitted light data of output bank note, the infrared transmission light data and curves of individual old coin is the curve 60 in Fig. 8 b, the infrared transmission light data and curves of two new coin is the curve 62 in Fig. 8 b, in Fig. 8 b, transverse axis is that length of paper currency, the longitudinal axis are transmitted light size of data.From the waveform of curve 60,62, can find out, although most of data are greater than the data on curve 62 on curve 60, because two curves have intersection, can not directly by the size discrimination of transmitted light data, go out two curves.Therefore, pass through formula
the weighted mean value that calculates transmitted light data, wherein, A represents the weighted mean value of transmitted light data, x
irepresent transmitted light data, w
irepresent transmitted light data x
icorresponding weights, all weights sums equal 1.By reducing the very big data of transmitted light data, weights corresponding to minimum data, thereby reduce very big data, the impact of minimum data on weighted mean value A.As shown in the figure, the weighted mean value of curve 60 is that the weighted mean value of straight line 64, curve 62 is straight line 66, as shown in Figure 8 b, between straight line 64,66, there is certain distance, can utilize the straight line 68 between straight line 64,66 to distinguish the data on curve 60,62, the corresponding weighted mean value of straight line 68 is and judges the whether satisfactory intensity threshold of transmitted intensity.If the weighted mean value of bank note to be measured on straight line 68, represents the weighted mean value that the weighted mean value of bank note to be measured is individual bank note, bank note to be measured is individual bank note; If it is the weighted mean value of two or multiple bank note that the weighted mean value of bank note to be measured under straight line 68, represents the weighted mean value of bank note to be measured, bank note to be measured is multiple bank note.
Because two or two above bank note cause that banknote thickness increases, and by obtaining the weighted mean value of bank note to be measured, contrasts itself and reference threshold, thereby judges whether bank note is re-opened when overlapping.By to bank note transmitted light data analysis, rather than directly to banknote thickness analysis, can overcome bank note medium aging, be stained with the impact on banknote thickness testing result such as dust, guaranteed the reliability of testing result.By removing the light activated easy transmission region of transmission, being difficult for to transmitted light is insensitive the scan-data that transmission region is corresponding, make transmission data mean value can reflect exactly the thickness of bank note, guaranteed the accuracy of testing result.
The execution sequence that picture size detection, safety line feature detection and the transmitted intensity of bank note detect can arrange as required.When any one testing result in three does not meet while imposing a condition, stuck banknotes to be measured is described; When three testing results all meet while imposing a condition, illustrate that bank note to be measured is individual bank note.Because multiple bank note are when overlapping, profile is not overlapping, the nonoverlapping probability of safety line is larger, therefore, whether overlappingly first judges that the physical dimension of bank note to be measured or safety line feature can be got rid of bank note fast, therefore the detection order that, the embodiment of the present invention provides is preferred detection order.
By the combination judgement to banknote image size to be measured, safety line feature and transmitted intensity, can accurately judge that whether bank note is overlapping, overcome bank note behaviour in service, the impact of bank note newness degree on testing result, improved the stability and the reliability that detect.
The embodiment of the present invention also provides a kind of self-aided terminal, and as self-help drawing money machine, self-help deposit machine or Self-service Tickets, this self-aided terminal has the pick-up unit of the stuck banknotes that above-mentioned arbitrary embodiment provides.
